Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

Students conduct a series of investigations on the unique properties of water. For this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students identify the characteristics and composition of emulsions. In this chemistry instructional activity, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Pupils design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.
